HDS02.1-W040N-HA12-01-FW
The HDS02.1-W040N-HA12-01-FW is a drive controller for the HDS Drive Controllers series from Bosch Rexroth Indramat. Installed between power supplies and servo or spindle motors, the unit translates motion commands into precise current and voltage patterns so each axis in an automated line follows its programmed profile. Within an industrial automation cell, it supports closed-loop control of speed, torque, and position to coordinate synchronized movement across multiple mechanical stations. It is intended for servo and spindle applications where changing loads must be corrected quickly to maintain commanded motion. In multi-axis equipment, this helps neighboring stations accelerate, hold speed, and stop in a coordinated manner.
Rated for a continuous output of 40 A, the controller can energize medium-power servo axes without saturating its output stage. This current is the maximum RMS value the connected motor windings may receive under normal duty. Command signals enter through an analog interface, allowing velocity or torque references to be supplied as ±10 V levels from a PLC or motion card. The analog input format also suits control systems that provide direct voltage-based reference signals instead of digital command channels. Thermal management relies on a built-in air blower, which forces air through the chassis to remove resistive and switching losses without external ducting. Forced internal airflow helps keep the heat sink and power devices within their intended operating range during sustained axis motion. The unit belongs to the DIAX04 controller family and uses standardized backplane connections for modular multi-axis assemblies. Its circuitry is optimized for air cooling, permitting cabinet installation while maintaining stable operation across the stated temperature range.
The unit is part of Line 02, indicating the second design generation with an updated component layout. The drive is Version 1. It mounts directly on a DIAX04 power rail and can be combined with matching DDS servo drives in a modular multi-axis stack. Its modular mounting arrangement supports compact cabinet layouts where several axes share a common supply section.
